CROSS REFERENCE TO RELATED APPLICATION

This application is a divisional of U.S. patent application Ser. No. 11/732,578 filed Apr. 4, 2007 which claims the benefit of provisional application No. 60/837,682, filed Aug. 15, 2006.

FIELD OF THE INVENTION

The present invention relates to a cosmetic display system comprising an applicator or an image thereof, a secondary package, and optionally a container and/or a handle.

BACKGROUND OF THE INVENTION

The cosmetic market is complex and sometimes confusing to consumers due to a variety of products that vary in form, benefits, implements, shades, pricing, and brands. Specifically, the mascara market may be confusing to consumers as they have to choose between product forms of regular, waterproof, washable waterproof, etc.; product benefits of lengthening, volume, curl, wear, etc.; and brush types of traditional, molded, straight, curved, etc. When questioned, over more than half of consumers indicated that they wished there was additional information at the store shelf to help figure out which mascara is right for them.

Specifically in the area of brush performance, most consumers agree that the mascara brush plays an important part in getting their desired look. Traditionally, cosmetic companies have placed a small image of the brush on the front of the secondary package to showcase brush design. However, few consumers agree that they can tell by looking at the monochromatic image of the mascara brush on the front of the package whether they will be able to achieve their desired look. A mascara brush is a small object having a lot of confusing surfaces that are hard for the naked eye to discern due to the close proximity of the protrusions and their wide range of radial angles. In recent years, molded brushes have become popular, in part due to the superior performance of some designs. The benefit of the superior designs can often be infered from the elements of the applicator like the stem or the protrusions. In the past, mascara applicators have used low chroma surfaces—various greyscale colors that cannot fully show the complicated geometry of many brushes. It has been discovered that color differences between different brushes elements can help consumers see the differences that exist.

Testing used to track eye movements of consumers when shown cosmetic display walls indicates that displaying the brush outside the mascara container garnered attention of consumers. Displaying a colored brush outside the mascara container clearly communicated a point of difference.

Now, it has been discovered that cosmetic display systems, such, for example, as those used for mascara application to eyelashes, can be improved by providing a cosmetic display system that highlights the brush to signal the benefit of the brush to the consumer. The present invention is directed to the representation of a cosmetic applicator in print on the package or in printed or project form on a surface in proximity to the product or a cosmetic applicator that is packaged outside the product container in order to provide a representation of the brush, thus giving consumers more of the information that they are seeking to assist in the purchase decision. Furthermore, the addition of color to the brush enables the individually defined protrusions or other elements on the brush to be more visible, and thus, more clearly convey the benefit of the shape thereof.

SUMMARY OF THE INVENTION

The present invention is directed to a cosmetic display system comprising an applicator or an image of an applicator, a secondary package, and optionally a container and/or a handle. The applicator of the present invention may comprise a substantially longitudinal stem having a proximal end and a distal end and a plurality of protrusions or indentations at the distal end of the stem surrounding a core, wherein the protrusions and/or the core are comprised at least one chromatic color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360; and a handle at the proximal end of said stem. The container of the present invention is structured to house a product and accept the applicator, and the secondary package of the present invention is structured to house the applicator by itself or the application and the container together such that the applicator and the container are displayed separately in the secondary package or a visual representation of the applicator shown at actual size in lieu of showing the actual applicator.

The cosmetic display system of the present invention is a unitary package comprising an applicator or an image thereof which comprises a display portion which connotes the ability of the package to clearly show to the consumer not only the package contents, but also the structure of the applicator, specifically the brush protrustions. The image of the applicator may be a real-like photo or any graphic representation. More specifically, the consumer may clearly discern shape, color, texture, and other components of the applicator. For example, the consumer can recognize the contrast between the applicator, protrusions, core, stem, handle, and container. The display system may show the actual applicator or an image thereof.

Thus, the present invention is directed to a cosmetic display system that highlights the applicator to disclose not only the overall geometry of the applicator, but also the details of its applicator portion, including the configuration of the protrusions or the relative size difference between the protrusions, if they are present, and the stem. The present invention is directed to a cosmetic applicator that is packaged outside the product container or an image thereof on the package or other medium in order to provide a real-life representation of the applicator, thus giving consumers more information at the wall that they are seeking to assist in the purchase decision. Furthermore, the addition of color to the various parts of the applicator enables the individually defined protrusions on the brush to be more visible. Hence, the colored protrusions or core promotes product recall for product identification. The colored protrusions or core can also act as a mechanism to communicate primary benefits (i.e., a pink brush may be marketed to indicate lengthening; red may indicate volume, blue may indicate waterproof, etc.).

There are several different techniques one skilled in the art may use to define the color parameters of the present invention. One such measurement technique involves the LCh color space where L is Luminance, C is Chroma, and h is Hue.

In this measurement technique, L refers to the perception of light intensity from no intensity to high intensity and may also be thought of as brightness. Black is the absence of light and would ideally have an L value of 0. Pure bright white is an intense, equal mixture of all visible wavelengths of light and would therefore have an L value of 100.

C, or chroma, is the saturation or purity of color. This number may be considered as the strength of a color, or its distance from gray. For instance, one can move from a light pink to medium pink to red as the chroma number increases.

The value h refers to the hue, or basic color, such as red, yellow or blue. Hue is defined in a plane with red, yellow, green, and blue being 90 degrees apart from one another. A color's hue is an angle in that plane.

These three variables of L, C, and h can be plotted in a three dimensional space using polar components where L is an axis, h is an angle, and C is the distance away from the L axis along the h angle as defined in the CIEL*C*h* color space system. It is important to note that both the illuminant and observer must be specified when describing the color of an object since both impact the color (i.e., a standardized observer, or reaction to spectrum, set of tolerances to different wavelengths of light and standard illuminant). CIELAB color space is used as a standard color space. When measuring color, controlled conditions are used with a standard observer (set of equations to standardize the sensitivity of a standard person for perceiving color spectra, and a standard illuminant, light source spectra). For purposes of this invention, a two degree observer is assumed and a D50 light source, but other light sources may be used such as incandecscent and fluorescent. Various pieces of equipment may be used for the measurement of color. One skilled in the art would use a spectrophotometer which is a device that will emit a standard light source, like D65, to the sample through a specific aperture and record the reflected spectra, preferably where the gloss angle is excluded. This spectra is then converted to an LCh color using standard observed curves like a 2 degree or 10 degree standard observer. Potential measurement devices include, but should not be limited to, an Ocean Optics' USB4000 fiber optic spectrophotometer or a Datacolor Microflash integrating sphere spectrophotometer. It is important to make sure that the device's aperture covers the entire measurement surface and that no light is allowed to either leave or enter the measurement area. If elements of an applicator can be separated and massed together, then a large aperture device can be used to characterize color whereby multiple bristles, for instance, are massed together to form an opaque pile whose color is then measured. This requires no color change be imparted to the applicator elements being measured (i.e., whitening caused by bending or deformation). Alternatively, a very small aperture device can be used to measure the LCh color directly on an applicator surface so long as source light is not lost from the sample (i.e., through gaps between the object surface and measurement device).

In the present invention, at least one part of the applicator (i.e. the protrusions, the core, the stem) is comprised of at least one chromatic color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. Specifically, the protrusions or stem or core comprise at least one chromatic color having a luminance value of greater than about 15; a chroma value of greater than about (22-0.22L) and a hue value of from about 0 to about 360. More specifically, the protrusions or stem or core comprise at least one chromatic color having a luminance value of greater than about 20; a chroma value of greater than about (22-0.22L) and a hue value of from about 0 to about 360. More specifically still, the protrusions or stem or core comprise at least one chromatic color having a luminance value of greater than about 25; a chroma value of greater than about (22-0.22L) and a hue value of from about 0 to about 360.

The protrusions or stem or core of the present invention may also comprise two or more chromatic colors each having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. The multiple chromatic colors may by on separate portions of the protrusions or stem or core or even on the same protrusion or stem or core.

The chromatic color of the stem may be the same chromatic color as the protrusions and/or core, or the chromatic color of the stem may be a different color than the protrusions and/or core. The stem may also be a non-chromatic color.

Also, the handle may be comprised of at least one chromatic color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. The chromatic color of the handle may be the same color as the protrusions and/or core and/or stem or the chromatic color of the handle may be a different chromatic color than the protrusions and/or core and/or stem.

Further, the container may be comprised of at least one chromatic color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. The chromatic color of the container may be the same chromatic color as the protrusions and/or the core and/or the stem and/or the handle or the color of the container may be a different chromatic color than the protrusions and/or the core and/or the stem and/or the handle.

The secondary packaging may be comprised of at least one chromatic color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. Preferably, the secondary packaging is at least partially transparent or translucent.

An additional aspect of the cosmetic display system of the present invention includes a design where the handle, the container, and the protrusions all are comprised of at least one color having a luminance value of greater than about 10; a chroma value of greater than about (22-0.22L); and a hue value of from about 0 to about 360. Further, the color of the protrusions, handle, and container may all be the same.

The various components of the cosmetic display system may be of matching or contrasting colors as defined herein. For example, the bristles and core may be contrasting colors; the bristles and stem may be contrasting colors; the stem and core may be contrasting colors; the bristles and secondary package may be contrasting colors; the core and secondary package may be contrasting colors; the stem and secondary package may be contrasting colors; the handle and container may be contrasting colors; the handle and stem may be contrasting colors; etc. Likewise, the bristles and core may be matching colors; the bristles and stem may be matching colors; the stem and core may be matching colors; the bristles and secondary package may be matching colors; the core and secondary package may be matching colors; the stem and secondary package may be matching colors; the handle and container may be matching colors; the handle and stem may be matching colors; etc.

Preferred protrusions of the present invention have the following LCh values: pink bristles: L=39.90; C=38.43; h=332.11; yellow bristles: L=79.57; C=88.74; h=87.78; black bristles: L=14.96; C=0.133; h=339.90; red bristles: L=29.37; C=39.80; h=20.05; green bristles: L=47.35; C=65.45; h=157.66.

The applicator may comprise multiple stems for example, but not limited to, an applicator with two application surfaces where there are two stems projecting from two opposing ends of a cylindrical handle. Alternatively, multiple applicators may be sold together where one or more of them contains color at the distal end. There can optionally be more than one container packaged in the cosmetic display system.

The brush of the present invention can be made by using a variety of techniques known in the art such as assembly of stacked disks, layer additive photocuring of suitable materials (for example stereolithography (SL)), or single/multiple part “injection molding.” Particularly, injection molding is, in essence, a process wherein molten plastic is deposited under pressure, or injected, into a closed form having a cavity of a desired shape, to fill the cavity, then cooled to solidify in the cavity, and then released from the cavity. One skilled in the art will appreciate that using the injection molding process, it is possible to form virtually any desired configuration of the protrusions, including the selected protrusions of the present invention. In addition, the injection molding technique allows one to control the length of individual protrusions, so that trimming of the finished brush may not be needed in order to form a certain cross-sectional profile of the brush.

The brush of the present invention, having discrete protrusions, can be made by an injection-molding process, for example using a multi-component molding injection machine. First, a hollow stem can be provided. The hollow stem can be made from any suitable material, for example, plastic or resin such as polypropylene, and may include any suitable thermoplastic or thermosetting materials. The hollow stem can be formed by injection-molding or any other means known in the art. The hollow stem may comprise any suitable shape in its cross-section perpendicular to the major axis, for example, cylindrical, rectangular, triangular, circular, polygonal, or any combination thereof, or any other shape, including irregular geometric shape.

Then, the stem can be disposed in an injection-molding form comprising a plurality of protrusion-forming channels. The protrusion-forming channels are disposed so that their entrances abut the hollow stem in predetermined locations in which the protrusions of the brush being constructed should be disposed after the brush has been constructed. The overall configuration and geometry of the protrusion-forming channels corresponds to the desired overall geometry and configuration of the brush being made. Each of the protrusion-forming channels terminates with an end and has a predetermined length. Depending on the size and length of the protrusion-forming channels, the protrusion-forming channels can be made by any means known in the art, for example using conventional drilling techniques, laser, chemical erosion, wire electrical discharge machine (EDM), or any other suitable means. The protrusion-forming channels can be formed, for example, by a plurality of coated plates disposed consecutively adjacent to one another, wherein mutually adjacent plates have surface patterns that form, in combination, a desired profile of the protrusion-forming channels.

In the next step, a second moldable material having a predetermined color can be injected, under pressure, into the hollow stem, to form the protrusions. The second moldable material can comprise the material identical to the first moldable material, or, alternatively, may differ therefrom, including in color. Only for the purposes of example, the second moldable material can comprise any suitable thermoplastic elastomer (TPE), such as, for example, styrene-ethylene-butylene-styrene (SEBS) block copolymer. In the described embodiment of the process, the pressure under which the second moldable material is injected should be sufficient to rapture the hollow stem and form perforations in locations corresponding to the protrusion-forming channels and further to fully fill the protrusion-forming channels with the second moldable material so that the second moldable material assumes the shape of the protrusion-forming channels. These perforations formed in the stem serve, in effect, as spinnerets for the second moldable material. The second moldable material that fills, under pressure, the selected protrusion-forming channels forms the selected protrusions that have external depressions described herein above, the depressions being a “negative” of the protuberances of the selected protrusion-forming channels.

After the second moldable material solidify in the protrusion-forming channels, the brush comprising the stem and the plurality of protrusions extending therefrom can be released from the injection machine. If the plurality of plates is used to form the protrusion-forming channels, the plates can be moved apart from one another, thereby releasing the formed protrusions.

If desired, an optional step of injecting a third moldable material into the hollow stem to fill the stem, can be used. When the process is completed, the protrusions are securely bound to the third material that has filled the stem. The third moldable material can comprise a material identical to at least one of the first moldable material or the second moldable material, or can be chosen to be different from either the first moldable material or the second moldable material.

This exemplary, non-limiting method of forming the applicator allows one to easily construct the applicator wherein the stem and the protrusions are formed of different colors.
